the first time write the binary coded decimal as input write its truth tablle to nine and after nine put the all position dont care to number fifteen same is also for excess three write its truth table to 9 and from 9 to 15 dont care then simplifiy each output coloumn by K_MAp to find out th circiut
In The Name Of GOD...
To convert from exs-3 to BCD it is obvious that you will subtract 3 from each number in excess-3 code;
Ex: to convert 1001 in excess-3 to BCD you will subtract 3=0011 from it so output is 0110...
HINT: for all digits>9 it is forbidden to convert to BCD... so you will have to convert from 0000 to 1001 only.

BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such
Multiply by 16. ANSWER: The answer is bcd 11 = 3 111 = 7 1111 i= F 01111 =E and so foirth
BCD codes,gray code,error detecting code,ASCII character code,Excess 3 code
BCD can be converted into 7segment display by using an encoder.
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc
i dont know 1001+1001 - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit. To change the circuit to an excess-3-to-BCD-code converter we feed BCD-code to the 4-bit adder as the first operand. Then feed constant 3 as the second operand. The output is the corresponding excess-3 code. To make it a BCD to excess-3 converter, we feed the 2's complement of 3 as the second operand. - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit.

explain decimal to BCD encoder
BCD codes,gray code,error detecting code,ASCII character code,Excess 3 code
it's your assignment do it by your self.
BCD-BinaryCodedDecimal->Binary equivalent of each decimalexpressed using 4 bits->For single digit decimal BCD is same as its binary.In BCD only first 10 binary numbers are valid.The remaining 5 are invalid. Gray code is an unweighed code. ex: G3=B3 G2=G3 XOR B2 G1=G2 XOR B1 G0=G1 XOR B0

BCD can be converted into 7segment display by using an encoder.
A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.
